What is included in the COMP Cams K-Kit?

This K-Kit is comprehensive, including the XE284H-10 camshaft, a full set of hydraulic lifters, valve springs, retainers, valve locks, and valve stem seals. It also contains a timing chain set, assembly lube, decals, and detailed installation instructions.

What kind of idle can I expect with this camshaft?

The XE284H-10 camshaft is part of the Xtreme Energy line and is designed for performance, which means it will produce a rougher, more noticeable idle compared to a stock camshaft. This is typical for cams with aggressive profiles used in street/strip applications.

What other modifications are recommended when installing this camshaft kit?

For optimal performance, it's recommended to pair this camshaft with an engine that has 9:1 or higher compression, a torque converter with a stall speed of 2800 RPM or higher, headers, and appropriate rear axle gearing. These components help the engine take full advantage of the camshaft's improved airflow and power characteristics.

Product Details

This COMP Cams K-Kit gives you everything you need to upgrade the valvetrain on your Pontiac 265-455 V8 engine. Inside this box, you'll find the XE284H-10 camshaft itself, along with a full set of hydraulic lifters, valve springs, retainers, and valve locks. It also includes valve stem seals, a timing chain set, and assembly lube to help with installation. Plus, you get decals and instructions to guide you through the process. This kit is designed for street/strip applications and works best with engines featuring 9:1 or higher compression ratios.

The XE284H-10 camshaft is part of COMP Cams' Xtreme Energy line, known for its aggressive lobe profiles that help improve airflow and power. This particular cam has a 240/246 degree intake/exhaust duration at .050 lift, which contributes to its noticeable idle and strong performance in the mid-to-upper RPM range. To make the most of this camshaft, you'll want to pair it with a higher stall speed torque converter (around 2800+ RPM), headers, and appropriate rear axle gearing. It's a popular choice for enthusiasts looking to extract more power from their Pontiac V8, and it fits a wide range of vehicles including the Pontiac Firebird, Grand Prix, and LeMans, as well as Buick Regal and Oldsmobile Delta 88 models.

Keep in mind that this camshaft kit is intended for performance builds and will result in a rougher idle than a stock camshaft. It requires a minimum of 9:1 compression to perform optimally. For installation, ensure you have the necessary tools and refer to the included instructions for proper timing chain and valvetrain setup. This kit is not CARB approved and cannot be shipped to California.
